### Email

The email linked to the user's account to be authenticated.

### Password

The user's account authentication password.

### Trigger ID (optional)

This will link the action with a [Action Listener](/firebase-auth-firestore-and-storage-plugin/plugin-elements/firebase-action-listener.md) of the same ID.&#x20;

If left blank, all listener on the page with blank ID's will be triggered at the same time, so we suggest to always define a Trigger ID.

When the function finishes running, it will trigger the [User Logged In](https://estare.gitbook.io/firebase-auth-firestore-storage-plugin/plugin-elements/firebase-action-listener#user-logged-in) event, storing the [User ID](https://estare.gitbook.io/firebase-auth-firestore-storage-plugin/plugin-elements/firebase-action-listener#new-user-id) and [User Email](https://estare.gitbook.io/firebase-auth-firestore-storage-plugin/plugin-elements/firebase-action-listener#new-user-email) on the listener's states.

***

## <mark style="color:blue;">Triggered events</mark>

Those events are triggered by an [Action Listener](/firebase-auth-firestore-and-storage-plugin/plugin-elements/firebase-action-listener.md) with the same ID as the [Trigger ID](#trigger-id-optional) provided on the action.

* User Logged In (if the action was successful)
* Error in Action (if an error occurs)
